Popis: Perturbation theory is used to understand the transitions that dominate photon-assisted tunneling in coupled quantum-well systems immersed in intense ac fields. In particular, we show that the Bessel functions, widely incorporated into models describing photon-assisted tunneling, correspond to net $n$-photon transition probabilities to virtual states, and that the argument of these Bessel functions is gauge dependent.
